head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
A forgiving kids' brawler whose depth is toy-combo and upgrade collecting.

Optimization · Practiced Mastery
A family-friendly open-world driving adventure romping through Springfield's mystery of cameras and cola.
Skylanders: Swap Force leans Optimization (Practiced Mastery); The Simpsons: Hit & Run leans Optimization (Practiced Mastery).
The Simpsons: Hit & Run leans a little harder on execution, though the gap is small.
Skylanders: Swap Force
Simple brawling tuned for children's reflexes
The Simpsons: Hit & Run
Forgiving driving and light platforming
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Skylanders: Swap Force
Enemies attack on basic scripts
The Simpsons: Hit & Run
No adaptive opposition exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Skylanders: Swap Force
Levels are fixed; only collectible spots are unknown once
The Simpsons: Hit & Run
Fixed missions with trivial traffic noise
The Simpsons: Hit & Run leans a little harder on optimization, though the gap is small.
Skylanders: Swap Force
Figure combos, upgrades and collectible routing are the depth
The Simpsons: Hit & Run
Mission routes, shortcuts, and collectible runs are solvable
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
